हुक आणि स्क्रॅप मानकांचे प्रकार

2021-07-03
च्याहुक is the main load-bearing component of the electric hoist, and it mainly has two forms: single हुक and double हुक.

Single हुक: It is a commonly used हुक with simple structure and convenient use. च्याmaterial is generally forged from 20# high-quality carbon steel or 20Mn, and the maximum lifting weight is not more than 80 tons.

Double हुकs: Double हुकs are often used when the lifting weight is large, and the force is even and symmetrical. च्याmaterial is generally forged from 20# high-quality carbon steel or 20Mn. Usually, double हुकs are used for lifting equipment larger than 80 tons.
च्याlaminated हुक is riveted by cutting and forming multiple steel plates. Since the हुक plate will not break at the same time, the working reliability is better than that of the integral forged हुक. च्याdisadvantage is that the weight and size are larger.

च्याscrap standard of हुक:च्याहुक is cracked; the dangerous section wears up to 10% of the original size; the opening degree is increased by 15% than the original size; the torsion deformation exceeds 10 degrees, the disadvantage is that the weight and size are large.
च्याहुक should be scrapped when one of the following situations occurs: 1. Crack; 2. Dangerous section wear reaches 10% of the original size; 3. च्याopening degree is increased by 10% than the original size; 4. च्याtorsional deformation of the हुक body exceeds 10; 5. Hanging च्याdangerous section of the हुक or the neck of the हुक is plastically deformed; 6. च्याहुक thread is corroded; 7. When the bushing of the हुक is worn to 50% of the original size, the bushing should be replaced; 8. च्याmandrel of the हुक is worn to the original size At 5%, the mandrel should be replaced.
